1.0 Introduction This manual describes the functional, mechanical and interface specifications for the following Seagate® LD25 Series SATA model drives: • ST9402115AS • ST920217AS Seagate LD25 Series drives comprise a new product category of 2.5-inch form factor drives designed for nonnotebook PC applications such as: • Consumer electronics (gaming, small PVRs/DVRs) • Ultra-small desktop PCs • Internet appliances LD25 Series drives are quieter, lighter and use less power than 3.5-inch drives. They are ideal for applications requiring the form and fit of a notebook drive but without some of the design specifications required by notebook drives such as high shock tolerance, high performance, and power management. LD25 Series drives are not presently suited for notebook applications or environments with high operating temperatures. These drives provide the following key features: • 5,400 RPM spindle speed • 2 Mbyte buffer • High instantaneous (burst) data-transfer rates (up to 150 Mbytes per second). • Tunneling Magnetoresistive (TMR) recording heads. • State-of-the-art cache and on-the-fly error-correction algorithms. • Full-track multiple-sector transfer capability without local processor intervention. • Quiet operation. • 500 Gs nonoperating shock. • SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns. • The 3D Defense System™, which includes Drive Defense, Data Defense and Diagnostic Defense, offers the industry's most comprehensive protection for disc drives. • Support for S.M.A.R.T. drive monitoring and reporting. • Support for Read Multiple and Write Multiple commands.
